The bottom line of the scrolling region (top of
the window is line 0).

the window is line 0).

Description |
|
The setscrreg() and wsetscrreg() routines set up scrolling regions in the windows stdscr and win, respectively. The dimensions of the scrolling region are defined by the top and bot parameters. If scrollok() is active, any attempt to move the cursor beyond the bottom margin of the scrolling region
scrolls the text in the scrolling region up one line.
The terminal screen produces a scrolling effect
if idlok() is also enabled.
